A changeset can be described as a separate working copy of the map where you can create, modify and delete objects or components without directly affecting the original data in the database.
All work in dpPower is performed in a changeset. Therefore, it is not possible to open the application without first selecting or creating a changeset. This is true even if you only want to search for, view or review information and do not have authorization to create or edit data.
When working in the application, changes are not saved directly to the database*; instead, changes are temporarily stored in the current changeset.
|
*Exception applies to object types with automatic posting, which is used in some modules, such as Operator. This allows users without posting rights to still use functions where the system automatically saves the changes to the database. |
Examples of changes stored in the changeset are:
•creation of new objects
•moving components
•updating attributes and forms
A changeset acts as a collection of all changes made during one or more work sessions. You can work with several changesets in parallel and use separate changesets for different tasks or projects.
For the changes to be saved permanently in the database, the changeset must be posted. Each changeset has a unique name and ID number to distinguish it from other changesets. Changesets can also be transferred between users as part of a workflow.
Key characteristics of changesets

Selecting and opening changesets
When you log in to the application, the Select Changeset dialog box opens automatically. The same dialog box can also be opened via the menu option File > Open... in the application menu bar.
The dialog box displays a list of the changesets you own, along with information about the name, comment and date the changeset was created.
In the dialog box you can:

oDetails - Show information about the changeset's properties, for example:
▪Whether it is optimistic or pessimistic.
▪How many items it contains.
